Nope. Magnet it out, spray the hole and the valve. Look to see if it has any burrs on it. If so polish it lightly with some like 600 grit or something light. Put it back in and install the solenoid. Some valves are held in buy a clip or roll pin and wont come out. In that case you can just push on the end of it with a small screw driver and it will spring back at you, if you don't feel comfortable taking the pin out. Its easy really.
